Wireless home theater headsets have been around for years, but they have only recently started to approach the sound-quality standards of corded headphones. If you've already spent thousands of dollars kitting out your home theater set, don't forget to make an investment on your headphones as well. Wired or wireless, a well-researched pair of headphones should last a lifetime and will let you hear every detail in the soundtrack, without the added worry of outside noise interfering with the performance.
